摘要

A method and arrangement for well completion and intervention operations whe re a workover riser (4) projecting from a wellhead (6) and up to a vessel (2) i s used, and where the upper portion of the workover riser (4) is designed to b e displaced from an upper position to a lowered position favourable for riggin g work, where at least the upper displaceable portion of the workover riser (4 ) essentially follows the heave motion of the vessel (2), whereupon the upper displaceable portion of the workover riser (4) is again raised to its upper position, the workover riser (4) being equipped with a telescoping connectio n (1).
